'Green' nightclub plans unveiled

The dancefloor will work by turning dance moves into electricity
A new nightclub in the Netherlands plans to offer clubbers an environmentally-friendly night out - in part by having them power the place through their dancing.

Plans for the Sustainable Dance Club in Rotterdam have officially been launched, detailing, amongst other things, a special dancefloor which converts the movement of the dancers into electricity.

Other methods of making the club "greener" include rainwater toilets, biological beer, and walls which change colour according to the heat generated inside the club, without using any electricity.

Professor Han Brezet of Delft University of Technology - which is acting as technical adviser to the project - told BBC World Service's Culture Shock programme that he had been overwhelmed by the interest when the plans were announced at a "premiere" event.

"When we had the premiere of the dance club, we expected 200 people to come - but we had to close the door early," he said.

"I'm surprised - but here in Rotterdam a new movement is coming up. It's the creative city, involving a sub-culture wanting to be sustainable but in a practical way."

Piezoelectricity

How the dancefloor will ultimately work is yet to be decided, professor Brezet added, although he stressed it has attracted a great deal of interest.

It is hoped that some practices can be applied in other nightclubs
"[It could be] to dance on the floor and you energise an electrical generator - but it could also be pneumatic, where you dance on some fabric and the air is pumped out and back again, like a pair of bellows," he said.

"Later on, you can use the pressurised air for micro-turbine and micro-generators."

But he added that in the long term, the club would have a special floor surface made of crystals that generate electricity in response to being stepped on - known as piezoelectricity.

"Mainly we are looking at people dancing - so it's about human power, human weight - what we call the 'jump dancing' to try to energise the floor and get electricity out of that," he said.

However, he warned that this would be "very costly".

Meanwhile, he added that he was hopeful some of the principles of the Sustainable Dance Club could be taken and applied elsewhere.

"In pop clubs, there is not so much attention on acoustics," he said.

"Design for efficient acoustics could reduce the power needed on stage."
